Impact Absorbing Traffic Noise Barrier System

Abstract

Disclosed is an impact resistant traffic noise barrier system. The system includes a traffic barrier that is designed to be placed adjacent a roadway and next to a flow of traffic. The design and weight of the traffic barrier permit it to withstand a variety of vehicle impacts. As part of the system, a sound wall is installed along the top of the traffic barrier. The sound wall includes a series of beams that are secured to the traffic barrier via anchor plates. Acoustic panels are secured between adjacent beams. An anchor cable extends from an anchor post, to a first post, and along a number of intermediate posts. The anchor cable is thus suspended above the traffic barrier with the anchor cable being connected to the beams. As such, the anchor cable suspends the beams in the event they become separated from the traffic barrier.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of, and claims priority to, co-pending Provisional Patent Application Ser. No. 62 / 613,821 filed on Jan. 5, 2018 and entitled “Impact Absorbing Traffic Noise Barrier System.” The contents of this co-pending application are expressly incorporated herein for all purposes.BACKGROUND OF THE INVENTIONField of the Invention[0002]This invention relates to a traffic noise barrier system. More particularly, the present disclosure relates to a traffic noise barrier that is designed to absorb impacts from vehicles.Description of the Background Art[0003]Noise barriers are commonly used along roadways. Noise barriers, sometimes called sound walls, are installed along roadways, such as interstate highways, county roads, streets and other thoroughfares. The noise barriers are used to acoustically isolate adjacent areas from sounds associated with automobiles, trucks, motorcycles, and other vehicular traffic. The area pr...

AI Technical Summary

Benefits of technology

The invention is a traffic noise barrier system that can withstand vehicle impacts. The system includes a crashworthy traffic barrier placed next to a road and a sound wall towering above it. The system uses a chain of interconnected beams and acoustic panels to absorb and dampen the sound waves generated by vehicles. The beams break upon impact to support the acoustic panels in place, ensuring safety and proper functioning of the system. The system effectively reduces traffic noise and provides safety for the surrounding environment.

Problems solved by technology

Placing the sound wall along the top of the traffic barrier can be problematic.

In particular, the sound wall can adversely affect the intended operation of the crashworthy traffic barrier.

Also, if the sound wall becomes detached from the crashworthy barrier, the vehicle, its occupants, or nearby pedestrians can become injured.

However, these reinforced barriers tend to be heavy, difficult to erect, and expensive.

Although the inventors of the background art achieve their own unique objectives, all suffer from drawbacks.

The background art all involve heavy, difficult to erect, or expensive designs.
